A pot experiment was conducted to study the antioxidant responses of tuberose treated with biocontrol agents and organic fungicide in combating wilt disease caused by Sclerotium rolfsii Sacc. The antagonists, Trichoderma viride4 (Tv4), Bacillus subtilis1 (Bs1) and Pseudomonas fluoresence3 (Pf3) were used alone and in combinations. Mahua cake was used as the source of organic fungicide. The treatment with the commonly used chemical fungicide, hexaconazole was taken as check. Among the fifteen treatments, soil application of Tv4 @2.5 kg ha-1 + Pf3 @2.5 kg ha-1 + Bs1 @ 2.5 kg ha-1 + Mahua cake @ 250 kg ha-1 recorded the highest enzymatic activities of peroxidase, polyphenol oxidase and phenylalanine ammonia lyase on the fourth day after challenge inoculation with Sclerotium rolfsii Sacc. This treatment also recorded the highest phenol content (1.179 µg g-1 FW) on the fourth day after challenge inoculation with S. rolfsii. This treatment recorded the lowest wilt incidence (7.56 %) which indicated 90.41 percent disease reduction over control.
